摘要： To provide a new dot pattern where a technology thereof is the technology to realize definition of information based on not an arrangement position of a dot, but a distance and direction between two dots, and as compared with the dot pattern of the above-mentioned previously existing technology, (1) reading is possible even when print resolution and read resolution are low, (2) a large information amount can be defined by the small number of dots, (3) decoding can be carried out at high speed, (4) reading can be carried out easily even when arrangement of an imaged dot pattern is deformed largely, and (5) decoding visually is difficult.
There is provided a dot pattern where at least one set of a starting-point information dot that is an information dot to be a starting point, and an end-point information dot that is an information dot to be an end point are provided, and the two or more information dots are arranged while an interval between information dots which adjoin each other in a prescribed order from the starting-point information dot has a prescribed distance value or prescribed distance value of a prescribed direction interval, and codes are encoded based on the prescribed distance value or prescribed distance value of a prescribed direction interval.

摘要： A system for producing rugate tags comprises a processor and an etcher. The processor is configured to determine an identifying data value. The etcher is for producing an identifier. The identifier comprises a rugate phase tag. The rugate phase tag encodes the identifying data value at least in part using a calculated rugate phase information.

摘要： The invention relates to encoding phase information in micro-grating-based anti-counterfeit devices such as diffractive optically variable identification devices (DOVID). The invention utilizes that alignment of grating line positions in different micro-gratings having common line spacing and orientation, can be used as a new, additional information channel in DOVIDs. By displacing grating line positions in different pixels relative to a common reference grating, relative shifts in alignment are introduced that do not affect the visual effects encoded in the DOVID. The relative shifts in line position alignment induce relative shifts in the phase of light diffracted by the DOVID, so as to introduce a spatial phase shift distribution corresponding to the distribution of position shifts over the DOVID. Such spatial phase shift distribution is not visible, and the phase encoded information is thereby invisible unless a reader based on e.g. generalized phase contrast is applied. The phase encoded information can further be phase encrypted so that a spatial phase modulator decryption key is required to read the encoded information.

摘要： A two-dimensional code having a rectangular region is provided. In the rectangular region, there are a plurality of code blocks, a first specific pattern, and error-correction code blocks. Each code block is composed of a plurality of cells aggregated together and formed to have both a specified corner in the rectangular region and the plurality of code blocks arranged in the rectangular region. The specific pattern is used to specify the positions of the cells. The error-correction code blocks are contained in the code blocks and formed to correct an error. The error -correction code blocks are arranged contiguously to part of the borders of the rectangular region. The part of the borders is displaced from the first specific pattern. Compressed data code blocks are also arranged in the same way as the error-correction code blocks.
